Debian DLA-2390-1 : ruby-json-jwt security update

high Nessus Plugin ID 141132

Language:

Synopsis

The remote Debian host is missing a security update.

Description

The json-jwt gem before 1.11.0 for Ruby lacks an element count during the splitting of a JWE string.

Therefore, there was a need to explicitly specify the number of elements when splitting a JWE string.

For Debian 9 stretch, this problem has been fixed in version 1.6.2-1+deb9u2.

We recommend that you upgrade your ruby-json-jwt packages.

For the detailed security status of ruby-json-jwt please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/ruby-json-jwt

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected ruby-json-jwt package.
